l Specication o f Letters. Patent Patented Feb. 4, 1913.

To all whom t may concern Be it known that I, ISAAC S. HENDREN, a

citizen of the United States, residing at Harrodsburg, in the county of Mercer and; State of Kentucky, have invented certain new and useful Improvements Measur-4 ing Instruments; and` I do hereby declare the following to be a full, clear, and exact? description of the invention, such'as will; enable others skilled in the artl to which it;

appertains to make and use the same.

drawings and pointed out in the claim.

My prime object, among others, isA to provide a measuring machine of absolute accuracy, whereby the exact distance traveled by the measuring wheel maybe readily determined and the work laid out ma be of a perfect level, or of any desired egree of inclination.

A further object of m Y invention is toV Other objects and advantages will be' hereinafter clearly set forth, reference being had to the accompanying drawings, in Which, i

Figure 1 shows a side elevation of my 1nvention complete, ready for use, and, Fig. 2

is a top plan view thereof.

In order to conveniently referto the various details of my invention and coperatingl elements, numerals will be employed,

., the same numeral applying to the corresponding parts throughout A the several views.

Referring in detail to the drawings,'1 indicates the rim of the measuring wheel, while 2 designates the spokes thereof,l said parts being made in any desired manner and of any preferred material and also of any size deemed most suitable for the result sought.-

I prefer to divide the circumference or rim of the wheel into ten equal parts.- I prefer also to employ ten spokes entering the rim at equidistant points vfrom each other,` the said spokes being preferably numbered from one to ten, I also kprovide a suitable hub formation,.as indicated by the plate 3 carrying the spoke. numbers from one to ten, asstated, and said hub is mounted upon a'Suit-able axle or shaft 4 of proper length to,extend outwardly on each side of the wheelv to afford la seat for the attachment ef the bifurcated balancing member 5, the branches thereof, 6 and 7, lying on opposite sides 'of the wheel and having their .ends properly connected to the spindle or y My invention relates to measuring instruments and more particularly to a tally` or,l numbering machine, the preferred materi-i alization whereof will be hereinafter fullyl set forth, illustrated in the accompanyingy axle 4 1n any'preferred way, as by the Aset ,screws 8, or equivalent means.

which I mount the numbering cyclometer or numbering machinevproper 1() of any desired character. -,Upon the housing 9, thus or otherwise provided, I secure the spring member 11, as by a suitable screw or rivet 12, as clearly shown, the free end of 4said spring extendin upwardly above the housingv9, whereby 1t will rest over the plunger 13 of the cyclometer or measuring instrument, it being understood that said plunger` is extended up through the housing 9 to lie in the path Vof the spring 11 and, in order tc actuate said spring andcolnmunicate movement to the plunger, I provide the finger or loin 14 having a'suitable anti-friction roller l5, said parts being so located upon the hub as to insure that it will come in contact with the upper side of the spring member l1 and force the same downward, vincidentally depressing the plunger 13 and, consequently, actuating the cyclometer.

I also provide a controlling handle fo my measuring instruments the same being designated by the numeral 16 and may consist of ay preferred construction, as wire of copper strength so shaped that the free ends thereof will engage each end of the spindle, lea-ving the remaining portion of the handle wholly out of contact with the' wheel, as fully shown in Fig. 2. 'Obviously the handle 16 may be moved over into a po` sition in front of the wheel, as indicated by the dotted line 16a so that, when in this position, the wheel will be reliably held upright.

The member 5 is provided with a handle member 17 which rests upon the same plane occupied by the lower side of the wheehand.

upon the handle thus constructed, I form the extension 18, the upper edge of 'which is erator therefore may 4readily determine whether the plane occupied by the handle and Wheel is horizontal or at an inclination, it being understood that suitable graduations may be provided upon the member 19 whereby the operator may at any time determine at a glance the character of the work ,he is measuring.

My numbering or measuring machine may be readily operated by grasping the handle 16 and causing the Wheel to travel upon the object to be measuredv .or graded, `when at each revolution of the wheel the numbering device or cyclometer will be guided through the mediation of the finger 14 coming in contact with the spring 11, vas before set forth.

It will thus be seen that l have provided a thoroughly reliable and eficient measurf ing instrument, which may be very cheaply manufactured and which will serve many uful purposes and believing that the advantages, construction and operation of my invention have thus been made clearly apparent, further description is deemed unnecessary.

What I claim as new is:

The herein described measuring machine comprising the combination of a carrying wheel, a graduated hub therefor, a spindle extending loosely through and beyond each end of the hub, a balancing member rigidly connected to the ends of the spindle, a controlling handle attached to each end of the spindle, a housing fixed to the spindle, a'

numbering device within the housing, a spring member carried by the housing, and an actuating linger carried by thephub to cooperate with said spring to depress the same land actuate the numbering machine carried within the housing.

In testimony whereof I have signed my name to this specification in the presence of tw'o subscribing witnesses.
